123    MatRegisterDynamic - Adds a new matrix type
124 
125    Synopsis:
126    PetscErrorCode MatRegisterDynamic(char *name,char *path,char *name_create,PetscErrorCode (*routine_create)(Mat))
127 
128    Not Collective
129 
130    Input Parameters:
131 +  name - name of a new user-defined matrix type
132 .  path - path (either absolute or relative) the library containing this solver
133 .  name_create - name of routine to create method context
134 -  routine_create - routine to create method context
135 
136    Notes:
137    MatRegisterDynamic() may be called multiple times to add several user-defined solvers.
138 
139    If dynamic libraries are used, then the fourth input argument (routine_create)
140    is ignored.
141 
142    Sample usage:
143 .vb
144    MatRegisterDynamic("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
145                "MyMatCreate",MyMatCreate);
146 .ve
147 
148    Then, your solver can be chosen with the procedural interface via
149 $     MatSetType(Mat,"my_mat")
150    or at runtime via the option
151 $     -mat_type my_mat
152 
153    Level: advanced
154 
155    Notes: ${PETSC_ARCH} occuring in pathname will be replaced with appropriate values.
156          If your function is not being put into a shared library then use VecRegister() instead
